Any equipment on each end is connected to a different phase.
There is a difference in the ground/earth/line voltages at each end, especially if there is a line fault or lightning strike.
Somebody puts a shovel through the cable, and shorts conductors.
Insulation resistance between conductors when water has crept into the cable.

Absolutely good thinking, hence my recommendation to use commercial optically isolated converters....
